What's worth watching, and what might not be, in prime time on Monday.

Little Big Town hosts this special, culled from the four-day Nashville festival inJune. Among those who took part are Dierks Bentley, Kelly Clarkson, Lady Antebellum, Miranda Lambert, Brad Paisley, Blake Shelton, Taylor Swift, The Band Perry, Carrie Underwood, Keith Urban, Lee Greenwood, Randy Travis and The Oak Ridge Boys. That doesn't mean all of them will show up on the TV show, obviously, but you'd have to think a lot of them will. And that possibility alone should make it worth watching for country music fans.

This documentary features bed-bound interviews with 10 couples, ranging from young lovers to spouses in their 90s, who discuss love, sex and infidelity for a film, we're told, that offers "intimate insights into what makes or breaks a relationship." Well, here's an insight into what can help preserve your relationship from breaking: Don't talk about your sex life on national TV. Tends not to help.

King & Maxwell | TNT, 10 ET/PT

Odds are more people will be watching the summer's biggest hit, CBS' Under The Dome (10 ET/PT) -- a good choice, probably, as in tonight's episode, Junior finally stands up to his father (who's even more insane than Junior, which is saying something). But thanks to DVRs, you can also check in on the season finale of this lightweight but pleasant summer diversion starring two of TV's more enjoyable performers, Jon Tenney and Rebecca Romijn, as mismatched private eyes.
